To all whom, it may concern.-

Be it known that l, ALFRED DOLGE, a citizen of theUnitcd States, residing at New York, in the county and State of New York, have invented new and useful Improvements in the lilanufacture of Felt, of which the following is a specification.

This invention relates to an improvement in that class of apparatus for manufacturing felt which is described in Letters Patent No. 311,809, granted to me March 31, 1885, as as signee of Carl B. Dolge.

The object of my present invention is to impart additional strength to the felt by making the same of longitudinal and of transverse webs, as hereinafter described.

My invention consists in certain new combinations of mechanism, as pointed out in the fo1- lowing specification and claims, and illustrated in the accompanying drawings, in which- Figure 1 represents a longitudinal vertical section in the plane 00 50, Fig. 2. Fig. 2 is a sectional plan or top view in the plane of section being indicated by the line 2 2:, Fig. 1. Fig. 3 is a transverse vertical section in the plane 9 Fig. 2, on a larger scale than the previous figures. Fig. 4 is a partial'side cle vation'looking in the direction of arrow 1, Fig. 2, on a larger scale than Fig. 3. Fig. 5 is a partial plan or top view of the parts shown in Fig. 4. Fig. 6 is a partial rear view looking in the direction of arrows 2, Figs. 2 and S. Fig. 7 is a partial transverse sectlon 1n the plane 00 a2, Fig. 4..

Similar letters indicate corresponding parts.

In the drawings, the letter A designates a table, and B B are two wool-carding machines of the well-known construction, which are situated on one-say the left-side of the table A, and which are intended to form the longitudinal bottom webs. O O are two other woolcarding machines situated on the right side of the table A and intended to form the longitudinal covering-webs. D is another woolcarding machine situated in the direction at right angles toward the direction of the carding-machines B B G G and intended to form the transverse web.

\Vith the carding mechanism of the machine D is combined acarriage, E, which is intended to carry the web formed by the machine D backward and forward over the table A, so that while the longitudinal bottom webs formed by the machines B B are drawn over the table A by the rollers a b 0, Fig. 1, in the direction of arrow 3, Figs. 1 and 2, the transverse web formed by the machine D is carried backward and forward in the direction of arrows 6 and 7, Figs. 1 and 2, and deposited upon the longitudinal bottom webs. As the longitudinal bottom webs, together with the trans verse layers deposited thereon, pass over the roller 1) they meet the longitudinal covering webs which are formed by the carding-machines O C and are carried by the endless apron (I over the roller 0, as seen in Fig. 1. The longitudinal bottom layers, the intermediate transverse layers, and the longitudinal covering-layers, after having been placed together as above stated, are carried off by the endless apron e,'which leads to the felting apparatus.

In the example illustrated by the drawings I have shown two cardingmachines, B B, for forming the longitudinal bottom layers, and two other carding-machines, O O, for forming the longitudinal covering layers; but it is not absolutely necessary to use two carding-ma chines B B, since one such machine may be sufficient, or the number may be increased; neither is it absolutely necessary to use two carding-machines O 0, since one such machine may be sufficient, or the number may be in creased if it appears desirable.

The transverse web formed by the carding machine D is carried back and forth over the longitudinal bottom webs, as above described, and for this purpose the web as formed by the cardingmachine is deposited upon an endless apron,,F, Figs. 1 and 3, with which is combined a carriage and a reversing-gear, as will be presently more fully described. In the example shown in the drawings said apron runs over rollers f g h t, Fig. 3, the shaft of the rollerf being journaled in a fixed frame, G, on which swing two bars, j, one on each end, which form the bearings for the shaft of the roller 9. The shaft of the roller It has its bearings in the carriage E, and from said shaft eX- tend two bars, 75, to the shaft'ofthe roller 9, said shafts being made to pass loosely through the bars. On the bars j are secured boxes which form the bearings for the shaft of the roller 71.

From this description itwill be seen that the four bars j is form a frame, which carries the rollers g and i, and which permits the roller h to followthe movements of the carriage E. This carriage moves out and in upon rails Z,- and as-it moves out in the direction of arrow 6, Fig. 3, it is exposed to a gradually-increasing force produced by the weight of the endless apron F and the frame which carries the same, and the power to move the carriage E inward would be much greater than that required to move said carriage out. In order to equalize this power, I have applied balanceweights m m, Figs. 2 and 3, which are secured to arms n n, firmly mounted upon a shaft, 0, which has its bearings in the frame G. On the ends of this shaft are firmly mounted levers p,

\ which connect by links q with the bars j.

(Best seen in Fig; 3.) When the carriage E is moved outward in the direction of arrow 6, the weights mm are lifted up, and the inward movement of said carriage is assisted by the gravity of said weights.

The web formed by the carding-machine D is carried to the endless apron F beneath a roller, 1", which is mounted in arms 8, secured to the bars j, Fig. 3, and as said apron passes the roller h the web is disengaged anddrawn down upon the table A, upon which it is spread by two rollers, t 1*, one of which acts upon the web during the outward and the other during the inward movement of the carriage. The shafts of the laying rollers 2% t have their hearings in slots formed in brackets a, which extend downward from the carriage E, so that said rollers can rise up as the thickness of the layers upon the table A increases, while they bear down upon the web 011 account of their inherent gravity.

The movements of the carriage E are produced by means of two endless belts or chains, H, which extend round pulleys 'v v mounted on shafts a'a*,' which-extend onopposite sides of the table A, said carriage being connected to the belts or chains by any suitable means.

On the outside of the frame which supports the rails Z for the carriage E, and also the table, is situated a slide, I, which is supported by brackets I), Figs. and 7, and which is provided with a groove, 0, to receive the heads of the set-screws e, which serve to retain and toadjust the tappets dd*. To the underside of the slide is firmly secured a hanger, J, Figs. 4 and 7, from which extends a link, K, to an arm, L, which is firmly secured upon the upper end of a vertical arbor, f, which is,

mounted'i-n suitable boxes secured to the outside'of the main frame, Figs. 4 and 5. On said shaft, near its lower end, is firmly mounted an arm, M, which connects by a link, 0, with a sleeve, [1, which is firmly secured upon a horizontal rod, h. This rod slides in suitable main frame.

brackets secured to the main frame, and it carries an arm, P, Fig. 6, in the upper end'of which is firmly secured a slide, i, which carries an arm, Q, in the upper end of which is firmly secured the belt-shipper R. The slide 11 moves in a bracket, S, extending from the The belt-shipper has two eyes, j j*, one of which carries the open belt T,

while the other carries the twisted belt On the main shaft are mounted two loose pulleys, 7U U jand two fast pulleys,VV*, and in the position shown in the drawings the open belt T runs upon the fast pulley, V, and the twisted belt T upon the loose pulley U*, and the carriage E moves in the direction of arrow 6, Figs. 2, 3, and 4.. From the side of the carriage projectsa pin, Z, Figs. 4 and 5,. and if this pin strikes the tappet d* the slide I is pushed out in the direction of arrow 6, and by means of the connections above described the rod h is moved in the direction of arrow 8, Fig. 6, and the belts T T are changed-that is tosay, the belt T is thrown upon the loose pulley U and the belt T upon the fast pulley V*and consequently the motion of the carriage E is reversed. If the felt to be produced is intended to be of uniform thickness throughout, the carriage E is caused to travel clear across the table A, -so as to carry theintermediate transverse web clear across the longi tudinal bottom web or webs; but if the felt is to be tapering in its cross-section, the tappet (W is moved toward the tappet d, so that the carriage E travels only partially across the table A; or if it is desired to make felt which is thickest in the middle and tapering toward both edges, the tappets d (1* are adjusted so as to cause the carriage E to travel over the cen tral portion of-the table only, as will be readily understood from the foregoing description.

WhatI claim as new, and desire to secure by Letters Patent, is

1-. The combination, with the carding-machine B and O and with the table A, situated between said carding-machines, of the cardingmaehine D, the endless apron F, the carriage E, and the reversing gear, substantially asdescribed.

2. The combination, with carding-machine D, the carriage E, the reversing-gear, and the endless apron F, of the slide 1, the tappets d d*, and suitable connections between the slide and the reversing-gear, substantially as described.

In testimony whereof I'have hereunto set my hand and seal in the presence of two subscrib-
